- Abstract
Usage of the secondary metal-working waste in production of the building materials, which are heat treated at high temperature, is urgent and perspective. After heat treatment at high temperature, the secondary waste does not contain harmful compounds any more that can affect health of people and quality of the environment. The waste becomes environmentally friendly, safe for storage and easy in utilization. The waste treated at high temperature does not contain aluminium nitride (AlN), ferric sulphide (FeSO3) and metallic aluminium (Al) any more, and the amount of ferric oxide (Fe2O3) is considerably reduced. Whereas, the amount of corundum (Al2O3) and spinel (FeAl2O4) is considerably increased. The earlier untreated or the specially treated secondary waste can be successfully used as one of the components, which significantly changes functional properties and application of the building materials heat treated at high temperature.
